Melocactus zehnerii is a Turk's turban cactus native to the state of Bahia, in north eastern Brazil. It is also known as Melocactus giganteus and Cactus zehntneri.[1] Like other Turk's turbans, it has a roundish lower body with typically about eleven vertical ribs which does the photosynthesis and an elongated upper body, the cephalum, which is a type of capitate inflorescence. Its phyllotaxis is much higher; usually 34/55. This upper cephalum can grow as much as 72 cm (28 in) in length, and displaying as many as 16 annual rings.[2] one of the longest living of all inflorescences known. This species was discovered in 1968 by Leopoldo Horst and A.F.H. Buining.
